WILLIAM A. CAMPBELL, OF IBELLFJFONTAINE, OHIO.

HEATING-STOVE.

Application filed August 27, 1'917.

To all whom it may concern Be it known that I, WILLIAM ii. CAMPBELL, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of (lhio, have made a new plan for certain improvements in 'i-leatingbltoves Adapted to be used in Furnaces or in Ordinary Rooms, 0f which the following is a specication of my furnace-stove, as set forth in application Serial No. 49,300, with additions thereto.

The object and nature of my furnace stove comprehends the utility for the great heat loss at the point of fuel combustion and heated products, by means which absorb, defleet, radiate and circulate the effect for .heating, and cooking purposes.

The specific nature of my invention in combination and detail of construction and special arrangement of its parts will be hereinafter fully described and specifically pointed out in the appended claims and illustrated in accompanyingdrawing, forniing a part of the specification and application, in which the figures show the plan of the arrangement and connection of the parts and the letters of reference indicate the same throughout/the drawings and specification.

Figure l is a vertical section of my furnace stove.

Fig. 2 shows a tubular hinge grate.

Fig. 3 illustrates the perforations and of the grate in which pipes are fitted thereto.

F ig. 4 is an elevation of the fuel chamber showing the supporting apertures for the radial intakes of the cross-Hue.

Fig. 5 is a top view of the furnace stove showing the plan of the heat ott-taires and the cooking shelves.

Fig. 6 is the horizontal top view of' the' tubular cross flue.

Fig. 7 is a sectional top view showing the smoke in-talre and oif-talre of the smoke flue.

Fig. 8 is a removable heat distributing hood with discharging olf-takes.

The fuel chamber wall is indicated by A composed of sections which are shown at a and a. These sections have in their uniting edges semi circular openings indicated at a5 which when joined form supporting apen tures indicated at B in the fuel chamber wall for the passage and support of the radial intakes of the tubular deiiecting crossflue, whereby it is centrally positioned within the fuel chamber with the fire; c? indicates the Specification of Letters Patent.

The tubular deflecting cross flue indicated by C is formed of horizontal radial intakes shown at c and a vertical oif-talre denoted by c2 in F l and i3 of the drawings. The function of this cross iiue provides a large, deflecting and circulating heating means, it being positioned directly with the heat source whereby it absorbs, deflects and radiates the heat effect to the rapid movement of the atmosphere therethrough,

The letter D indicates a superheating chamber formed with a receiving intake in its bottom, shown at d, and the top open, the wallhaving a flanged edge denoted by d3 and a register discharge at the topfshown at ab. Cooking register shelves are indicated at d5 in the upper portion of the superlieating chamber illustrated in Figs. l and 5 of the drawings.

Th's superheating chamber has three dis tinct functions of utility; it communicates with the discharge entf-taire of the crossiue; it provides a large deiiecting and radiating surface by its extended bottom and wall, which contines the heated products between its wall and the upper stove wall, shown at causing the eifects of the products of combustion there around better radiation; and the upper portion of the interior chamber provides warming and cooking means therein.

The letter indicates the radiating sinolre flue of the stove top is formed-by two concentric walls with its intake, denoted at e in the bottom inline above the fuel intake and with its oiftalre-shown by e1 positioned at the opposite diameter point from the intake in flue wall as illustrated in Figs. l, 5 and 7 of the drawings. The function of this flue is to prevent smoke escape at the fuel intake; and cause the movement of the heated products of combustion to pass from rear to the front in the upper chamber of the stove; and producing greater radiating effeet therefrom.

The letter F, indicates the peripheral register offetalre, whose function is to discharge the heated atmosphere from between the upper stove wall, Gf and the supplementary casing H. rihe said wall and casing is secured to the stove top by suitable means not shown. The letters fr. and h1 indicate the grate, shown in atmospheric intakes in the bottom of the supplemental casing; and the intake t is adapted to be connected with otherl tubular intakes as need may suggest; h2 indicates a heat distributing hood having discharging ofl-takes shown at k3 illustrated in Fig. 8.

This removable heat distributing hoodie adapted for furnace use, when suita ly iitted to the upper peripheral surface of the steve top (indicated by dotted lines in Fig. l). The lette/i1 l indicates a hinged tubular or pipe grate formed by circular perforated rim shown at la, and the hinge illustrated in Figs. 2 and 3 of the drawings, 7c3 denotes the hinge rod and h4' the adjusting chain. The function of this grate provides greater durability, is easily repaired and permits the easy removal of clinkers or other obstructions. The letter L shows the ash pit and Z the door. Arrows indicate the heat and atmospheric movements.

This removable heat distributing hood in.- dicated by F ig. 8, and by dotted lines in Fig. l, of the drawing, is adapted for furnace use, when suitably fitted to the upper peripheral surface of the stove top, whereby the local heater having shelves may be convertedinto a furnace heater, from which the heated air may be distributed to remote parts of the building.

From the foregoing description of my new furnace stove and illustrated in the companying drawings the principal and peculiar features of merit will be comprehended.

Having Vthus described my invention, what I claim and desire to secure by Letters Patent, is,-

1. In a furnace stove of the character described in combination with a stove wall, of a delecting super-heating chamber formed with an intake in the bottom and the top open, the edge of wall flanged outwardly provided with a register and shelves within; of a stove top formed with a ring shaped smoke 'flue wall and a peripheral register ofltake, the smoke flue havin g the smoke intake in the bottom above the fuel intake and the discharge velftake oppositely disposed in flue wall, said wall having a projecting rim in inner top which provides support for the flanged edge of said chamber wall and register thereon; of a deflecting radiating cross liue formed with horizontal radial intakes and a Vvertical oiftake; of a fuel chamber Wall having supporting apertures formed therein, the said super-heating chamber having support and connection with the said stove top and with the olftake of the said cross iiue, the radial intakes of the said cross flue having support and connection with the apertures of the said fuel chamber wall, whereby the intense heat effect of the fuel ycombustion may be absorbed, radiated and circulated, as and for the purposes specified.

2. ln a furnace stove of the nature described in combination with a stove and casing wall, of a stove top formed with a ring shaped smoke flue wall and a peripheral register offtake, the smoke line having the in.- take in the bottom above the fuel intake and the discharge oiltake oppositely disposed in wall, said wall having a projecting rim in the inner top adapted to support the wall and register of super heating chamber; of a deecting super heating chamber formed with an intake in the bottom, the top edge of wall flanged outwardly, the top open pro` vided with register and shelves within; of a deilecting cross flue formed with horizontal radial intakes and vertical oiltake; of a fuel chamber wall having supporting apertures formed therein, the said stove top having connection with a stove and casing wall and with the said super heating chamber wall, the intake of the said chamber having support and connection with'the offtake of the said cross flue and the radial intakes of it having support and communication with the supporting apertures of the said fuel chamber walhwhereby the heat effect of the fuel combustion may be used for the purpose set forth.

3. In a furnace stoveof the character described in combination with a stove top, of a removable heat distributing hood formed with heat olftakes in the top and the bottom an open intake; of a stove top formed with ring shaped smoke i'iue Wall and a peripheral register heat oltake, the luehaving the smoke intake in the bottom above the fuel intake, and the smoke ofltake oppositely disposed in the flue wall, the said hood having secured connections with the said stove top, whereby the local heater may be converted into a furnace heater from which the yentire heated air may be distributed to remote parts, as specified.
